Ride - Handling

[gunay]

I had a auris d4d in Turkiye. Ride is perfect but handling has some problems. Due to soft springs and high height (these properties may depend on country, europen auris may be has diffrent specifications), the handling is bad especialy at high speeds(120-150km/h).

The sport springs are 3cm shorter than original ones and in this case i will have problems on rough roads.

Is rear spoiler increase handling of vehicle?

Not too much to make a difference, it's not a wing... Most of the spoilers are like that, just for aesthetics.

If you want to improve handling, you have to get sport springs. If you don't want to, because of the rough road conditions, then you can either try finding a way of installing a rear wing, which is pretty darn hard and most likely to look hideous, or just ease up on the steering wheel at high speeds.

My expirience and as far I know it depends on the country. The sport springs are shorter but the suspention is harder, the car stays closer to the ground and it is more stable. It is got better handling and on rough roads it is not that comftable. The rear spoiler- yes, if it's the proper one it pushes the car slightly down to the ground making it more stable on the road and easy to handle.

Spoilers will not help IMO (unless you corner at and above 70mph on a race track :o )

Edit: 150 km/h = 93.2056788 mph you can not be serious! A rear spoiler may help but it is likley add unwanted understear and I suspect your problem is tyre related...

Are you referring to the rear wobble when cornering (I hate it), this can be fixed with more pressure. Try running your rear tyres at 34psi to stiffen up the rear depending on the tyre (and the fronts should be 38psi) and check pressure every month or until the wobble re-apears. To run these higher pressures you need a softer compound to be safe (Dunlop Sport, Eagle F1 etc...) or medum compound Falken FK452 if you like your tyres to last and the Falkens are my choice of tyre.
